Abstract Due to the semi-arid climate, scarcity of vegetation, the presence of a sometimes steep slope, Algeria is vulnerable to soil erosion that threatens its socio-economic development. In the watershed of K’sob, transport of suspended sediment by rivers is a disturbing phenomenon due to siltation to 80 % of the dam at the outlet. Data of suspended sediment concentrations are closely related to liquid discharge (Q). Models of solid discharge (Qs) according to the equation Qs = aQb were used to perform qualitative and quantitative analysis of suspended sediment. Different scales of analysis helped identify and explain conclusively seasonal models. Sediment production is very high in the fall. In the spring, despite the increase in discharge, it is less significant. In summer, during a period of disappearance of vegetation cover, highly loaded floods are sometimes observed. Currently, millions of cubic meters of sediments are dredged each year. This large volume is an economic, environmental and ecological problem. To remedy this, an experimental study of manufacturing brick has been proposed with 65 % of sediment, 25 % of dune sand used as an additive and 10 % water. The shrinkage is minimal for a solid brick fabricated to 800 °C during 6 h of cooking. The mechanical tests carried out on the brick exhibit acceptable values of compression strength, mass density and water absorption. The study of the evolution of these parameters for different pressing intensities (13.2–20–30 and 40 kN) at different ages (4, 14, 21, and 28 days) shows that the solid brick acquires its resistance only after 21 days.En raison du climat semi-aride, de la pauvreté en végétation, de la présence parfois de pente abrupte, l’Algérie est très vulnérable à l’érosion des sols qui menace son développement socio économique. Dans le bassin versant du K’sob, le transport des sédiments en suspension par les cours d’eau est un phénomène préoccupant en raison de l’envasement à 80 % du barrage situé à l’exutoire. Les données de concentrations de sédiments en suspension sont étroitement liées aux débits liquides (Q). Les modèles de débit solide (Qs) suivant la relation Qs = aQb permettent d’effectuer une analyse qualitative et quantitative du transport solide en suspension. Les différentes échelles temporelles d’analyse utilisées ont permis d’expliquer et d’identifier de manière assez concluante les modèles saisonniers. La production des sédiments est très forte en automne. Au printemps, malgré l’augmentation des débits, elle est moins significative. En été, période de disparition du couvert végétal, des crues fortement chargées sont parfois observées. Actuellement, des millions de mètres cubes de sédiments sont dragués chaque année. Ce grand volume représente un problème à la fois économique, environnemental et écologique. Afin d’y remédier, une étude expérimentale de fabrication d’une brique a été proposée avec 65 % de sédiments, 25 % de sable de dune utilisé comme additif et 10 % d’eau. Le retrait est minimal pour une brique pleine fabriquée à 800 °C pendant 6 h de cuisson. Les essais mécaniques effectués sur la brique présentent une résistance à l’écrasement, une masse volumique et une valeur d’absorption d’eau acceptables. L’étude de l’évolution de ces paramètres pour différentes intensités de pressage (13.2–20–30 et 40 kN) à différents âges (4, 14, 21, et 28 jours) montre que la brique pleine fabriquée n’acquiert sa résistance qu’au bout de 21 jours.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
